The St. Tammany Sheriff's Office has lifted the emergency lockdown at two Slidell schools, Boyet Junior High School and Little Oak Middle School, which share a campus on Rebel Drive.

Capt. George Bonnett, spokesman for the Sheriff's Office, says that the move was precautionary after a "suspicious incident."

The schools were locked down for about an hour and a half.

As the lockdown was lifted, Sheriff Jack Strain said deputies were called to the scene after a parent saw someone walking near the campuses with what appeared to be two rifles.

After the parent reported the incident to a crossing guard, authorities locked down the school and deputies began swarming the area.

Deputies searched the schools and surrounding areas, eventually discovering a pair of air rifles inside a home near the building, Strain said. The home had been left unlocked and the air rifles were left just inside the door, he said.

A student at Boyet told investigators he had been bringing the air rifles to his house earlier in the day, Strain said.

No one on campus was injured during the lockdown.

Once the lockdown was canceled, parents of students at both schools arrived at the school in large numbers to begin checking their children out of school for the rest of the day. However, classes were continuing as scheduled.

The Sheriff's Office has scheduled a press briefing on the incident for later Friday morning.
